There’s been a lot of buzz about Passbook and the excitement continues to go around the spectrum of actually having Passbook passes in a user’s device. The end product, which are digitized Passes, is what makes Passbook appeal to everyone. And for businesses, it’s providing this end product to their consumers that will distinguish them from competitors who don’t supply it. To make this business goal a reality requires a Passbook API.
An API or Application Programming Interface is simply a tool that grants other websites, applications, or devices access to its functions. Many companies publish their APIs; in turn revealing the coding and language that enables functionality of their product or service. It is a set of instructions that allows one software program to interact (interface) with another software program keywords search volume api.
To illustrate, Twitter is a website that people go on to tweet pictures, messages, and other things to connect with their social network. It began as a website only, but once a number of Twitter APIs were released, its service is now not just limited to websites. Twitter can be accessed on mobile devices like smartphones and tablet computers, and individual applications on desktop computers. In order to get access to Twitter on those devices, an API is needed. It allows the external app or device to communicate with the backend systems.
APIs are great in a sense that it creates various channels for the product or service to be filtered through — via apps, desktop software, web browsers, or mobile devices. Not only does it serve as a way to access the initial product, but with the API, developers or individuals can extend and build upon it. Think of the API as the framework for how a certain service works. With this can spur innovation for creating new ways to use the service and enhancing or adding additional features to the original version. That is what makes every API unique as developers come up with unique ways to channel or present the product.
For Apple, Passbook is an individual app that stores digital versions of passes. There needs to be a channel in which passes can be created, distributed, and updated to the app itself. The API contains the information for Passbook to communicate with the external world, with the proper coding and language that enables those functions. With the API, people can extend upon the original capabilities and add multiple innovative features that can be implemented for use.
